' T OFFICE 3 Claims.

My invention relates to improvements in water heating apparatus and theprincipal objects of my invention are directed to the provision of awater heater which is constructed from a relatively few parts which areeasily and readily assembled so as to make it all the more possible toprovide a low cost heater.

According to the invention, the parts are so constructed and so arrangedas to facilitate the quick heating of water with a low fuel consumption,and thereby to provide a low cost of operation.

It is another object of my invention to provide a novel and improveddevice which may be made more economically and with fewer operations inthe manufacture of parts, as well as in assembly thereof, than priordevices known in the art.

Among the other various objects of my invention are: first, to simplifythe construction;

second, to secure a high degree of accuracy in the performance of thework; third, to attain a high degree of speed in the construction of thedevice due to its simplified construction; fourth, to attain aflexibility or capability of adjustment by which a large variety of workcan be produced on the same machine; and fifth, to attain an ease inadjustment and in repairs for the device.

With the foregoing and various other novel features and advantages andother objects of my invention as will become more apparent as thedescription proceeds, the invention consists in certain novel featuresof construction, and in the combination and arrangement of parts as willhereinafter be more particularly pointed out in the claims hereuntoannexed and more fully described and referred to in connection with theaccompanying drawing wherein:

Fig. 1 is a sectional elevational view through a water heater embodyingthe novel features of my invention;

Fig. 2 is a sectional plan view on the line 2-2 of Fig. 1; and

Fig. 3 is a plan view of one type of fuel burner which may be used withthe heater of my invention.

Referring now to the drawing more in detail the invention will be morefully described. Like numerals refer to like parts in different figuresof the drawing.

A casing is formed from an outer annular wall 2 with which is associatedan inner wall 4 spaced therefrom by means of upper and lower walls 6 and8 to provide an annular water chamber 10 and a compartment within theinner wall 4, as

shown. The upper portion of wall 4 which is indicated by l2 inclinesinwardly, substantially as shown.

An inner water compartment M which is. disposed within the inner wall 4has spaced outer and innerwalls l6 and [8 which are connected to 5 eachother by upper and lower walls 20 and 22. This compartment is supportedby lugs 24 disposed thereon which rest on lugs 26 disposed upon the wall4. In assembling the device, the inner water compartment may be movedupm wardly within the compartment and may be rotated sufiiciently tocause the lugs 24 to overlie the lugs 26.

The outer wall N5 of the inner water compartment inclines outwardly andupwardly from its lower end to a point intermediate its ends so as toprovide a gradually narrowing passageway 28 between it and the wall 4.The upper portion of said'wall I6 is disposed relative to the wallportion I2 to carry out the narrowing passageway effect. 01

Theinner wall l8 inclines inwardly and upwardly, to form a taperingspace l9 with the upper wall inclining outwardly all as shown in Fig. 1of the drawing.

A base 30 at the lower end of wall 2 is adapted to support a burner 32.The burner 32 is a gas burner and has two or more concentric hollowportions 34 and 36 provided with outlets for gas. Any other typeof'burner may be employed if it is desired. 30;

Horizontally extending fins or ribs 38 are provided on the wall It.These are disposed in the passageway 28. Other fins 40 extend inwardlyfrom wall [8. The products of combustion flow upwardly throughpassageway 28 and space I9 35 so that heat is absorbed by fins 38 and 40and transferred to the water within compartment [4. Also heat isabsorbed by wall 4 and transferred to water in space H].

The fins and narrowing passageways and space l9 function to restrict thefiow of gases to bring about the desired heat transfer to the water. Abaflle 42 at the upper end of space l9 has an upper plate 44 and outlets46 which tend to restrict the flow of hot gases. A dome 48 at the upperside of the heater has an outlet for connecting the same to a flue pipeor the like.

The arrangement is such that the bafile 42 directs the flow of hot gasesonto connections 54 and 56 which tends to increase the efiiciency of theheater by utilizing such gases which would go to waste were they to flowdirectly out the flue.

As stated above, the inner water compartment I4 is easily insertedwithin the compartment 55 formed by the inner walls and is supported bymeans of engaging lugs 24 and 26. To center the compartment I4,abutments or bosses 50 may be provided on some one of the ribs 38 whichengage the wall 4.

A tube 52 extends downwardly in the inner compartment l4 and saidcompartment is connected to the water space ID by connections 54.

A connection 56 extends outwardly from the water space Itat the upperside of the heater by connection 60 and a connection 58 leads into thewater space at the lower side of the heater. By means of theconnections, the water heater may be connected to a hot water storagetank or to the cold water supply and to the hot water system whereby inthe operation of the heater water circulates in and through the heaterwherein it is heated.

While I have described the invention in great detail and with respect tothe present preferred form thereof, it is-not desired to be limitedthereto embodied in other specific forms without departing from theessential characteristics thereof. The present embodiments are thereforeto be considered in all respects as illustrative and notrestrictive, thescope of the invention being indicated by the appended claims ratherthan by the foregoing description; and all changes'which come within themeaning and range of equivalency of the claims are therefore intended tobe embraced therein.

' What it is desired to claimand secure by Letters Patent of the UnitedStates is:

1. A'water heater comprising in combination, a casing including outerand inner spaced vertical cylindrical walls connected together at upperand lower ends forming an outer annular water space arounda verticallyextending chamber open at upper and lower ends, a separable cylindricalunitary member insertable in and removable from said chamber through anopen end thereof including spaced concentric outer and inner wallsintegral with upper and lower ends forming therewith an inner annularwater space and an 2. A water heater comprising in combination, a casingincluding outer and inner spaced vertical cylindrical walls connectedtogether at upper and lower ends forming an outer annular water spacearound a vertically extending chamber open at upper and lower ends, aseparable cylindrical unitary member insertable in and removable fromsaid chamber through an open end thereof including spaced concentricouter and inner walls integral with upper and lower ends formingtherewith an inner annular water space and an inner upwardly extendingcentral passageway, engageable means associated with said firstnamedinner wall and the outer wall of said member for supporting the memberwithin said chamber with said outer and inner walls in spaced relationforming an outer upwardly extending annular passageway therebetween,connections between said water spaces, and fins spaced upwardly of andextending outwardly from the walls of said member partially restrictingsaid outer and central passageways, the outer and inner walls of saidmember arranged in diverging relation from the lowerends thereof wherebythe outer and central passageways are gradually narrowing upwardly fromthe lower portions thereof.
